This is the song divorce that doesn't end…yes it goes on and on my friends! Show of hands, who thought Bethenny Frankel and Jason Hoppy's divorce proceedings would go as smoothly as they both initially promised? Yeah, that's what I thought.

The battle for Bryn is now amping up as both Bethenny and Jason have filed for primary custody. Jason seems to want more stability for his young daughter, while the reality star/talk show host wants mommy-daughter bonding to occur while flitting around the world. Hmmm…middle ground shouldn't be too hard to find with these two. #goodluckhoppyyouregoingtoneedit

According to Radar Online, the gloves are coming off, and just in time for Jason to say g'day to his ex-wife's plans to take Bryn Down Under. A source tells the site, “Jason won’t let Bethenny take Bryn to Australia. He doesn’t think it’s good for their little girl to travel half way around the world with her mom on a business trip. How much time will Bethenny actually be able to spend with Bryn because it’s definitely a working trip? It’s causing nothing but more stress to the divorce proceedings, which have turned extremely hostile. Bethenny’s lawyers are considering going to court to see if they can get a judge to sign off on her taking Bryn to Australia."

The insider explains that Bethenny's reasoning for filing for sole custody was so that she could take Bryn with her on all of her business trips. The source reveals, “Jason wasn’t letting her take Bryn on trips. Jason didn’t oppose Bethenny taking Bryn to Aspen during the Christmas holiday, but after that trip things went downhill quickly. Bethenny told Jason about her plans to take Bryn to Australia, and he immediately voiced his disapproval. No one says no to Bethenny, it’s just not a word she is accustomed to hearing. She could see that Jason was going to stand in the way going forward, and this is the reason why she wants sole custody. She doesn’t want a battle every time she goes on a trip."

Fear not, though. It's not all custody battles and solo business trips for the reality star turned self-help/cocktail/book-writing maven. Perez Hilton is reporting that Bethenny has a sixth book deal in the works. I'll bet you'll never guess what it's about! Kidding…I know y'all are sharp. You all called it when the divorce gossip began–Bethenny is going to make a fortune touting the single life. Her newest tome will discuss how she deals with life as a single mom. Sigh.

A Bethenny source claims, “Bethenny has been writing and documenting her feelings in the beginning stages of the divorce. The book will explore the struggles and compromises all single moms face. It will deal with the delicate balancing act that is being a single mom, and the guilt she feels because her daughter Bryn will now come from a broken home, something she never wanted for her little girl.”

Cue the violins…as if she's the first single parent in history. Do NOT, however, mistake my sarcasm for hatefulness. I can't begin to fathom how horrible it is to go through a divorce, much less be a single parent, and I realize that no amount of money makes it easier. It just seems that Bethenny's plans to become a champion for single mothers everywhere is just a transparent business ploy. Of course, I could be very wrong…it wouldn't be the first time!

Well, that was quick! I couldn't even type out my diatribe without Bethenny responding to the book rumors on Twitter! When asked point blank by a follower if Bethenny was writing a book on single motherhood, she replied with a resounding "Nope." She also reminds her fans not to always buy into tabloid rumors. Oops!
